网上自主学习模式是高校教学改革的有效方式之一，对网上自主学习的方式、效果、利弊及适用人群进行探讨。以科技论文写作知识的学习为例，建立网上自主学习的平台，制作专题学习网站，在石家庄铁道学院的研究生中进行试验教学，对网上自主学习模式的学习效果和认可程度进行分析，得出结论：网上自主学习是可行的，必要的，有助于提高学生自主学习能力，适用于大学高年级及研究生等自控能力和自学能力强的群体，应有针对性地积极落实实施，取得满意的教学效果。     

资产专用性与交易成本节约——论企业是信用的载体

企业的功能不仅在于节约要素(中间品)交易成本,是要素的"间接定价装置",还在于节约最终产品交易成本.信息不对称的产品市场上,企业在交易中"制造"了一个重复博弈机制,这使其更关心长远利益.它用自身专用性资产--从价值和数量两个维度--来作为其产品是合格品的担保.专用性资产单位价值越大,数量越多,企业越有谋求长远利益、放弃短期机会主义行为的激励.市场上理性的买方考虑到这一点,总是认为效益越好、规模越大的企业越有可能提供合格品.企业是信用的载体,它一定程度上避免了产品市场由于信息不对称所引致的逆向选择,从而节约最终产品交易成本.我们的分析补充和完善了企业的交易成本理论.     

Do the magnitude and asymmetry of specific asset investments matter in the supplier–buyer relationship?

Abstract

Despite a body of literature on specific asset investments, the extant literature falls short of exploring the magnitude and symmetry of specific asset investments in supplier–buyer relationships. This paper builds on prior research to identify and examine the impact of total and asymmetric specific asset investments on commitment, trust, and conflict in supplier–buyer relationships. Covariance structure analysis is used to analyse survey data. The results show that total SAI are positively related to commitment and trust, while asymmetric SAI are negatively related to trust and positively related to conflict in supplier–buyer relationships. Decision-making uncertainty affects trust, commitment, and conflict more than any other variables. Therefore, firms should work to strengthen their relationships by increasing the magnitude of specific asset investments with the aim of increasing trust and commitment. We also discuss the limitations of this study and suggestions for future research.

新审计报告与资本市场的信息反应——来自股价同步性和股价预测能力双维度的经验证据

新审计报告准则的施行旨在增加审计报告的信息含量及其决策相关性。以2015—2018年沪深非金融上市公司为样本,研究发现新审计报告施行后,上市公司的股价同步性显著下降,公司特质信息含量比例显著上升,股价特质信息效率显著提升,同时新审计报告的施行产生了增量信息。在此基础上,进一步分析新审计报告准则对资本市场特质信息效率的传导机制,发现投资者关注度对新审计报告(关键审计事项的披露数量)影响资本市场特质信息效率的过程中表现出显著的部分中介效应。分样本检验的结果表明,虽然AH股共同上市公司和非AH股共同上市公司之间的结果存在细微差异但整体趋势相似。通过对新审计报告的影响的分析,可以更好地理解该政策对资本市场的影响。     

EMNEs venturing into advanced economies: Findings from comparative cases of two Indian MNEs

Indian firms are challenged by the latecomer disadvantages faced by emerging‐market multinational enterprises (EMNEs) in general. These challenges notwithstanding, Indian firms are doing cross‐border acquisitions (CBAs) in developed regions. Analyzing firm‐level secondary data of two Indian MNEs—namely, Motherson Sumi Systems Limited and Rain Industries Limited—that show significant developed region–based revenues and assets, we link extant and emerging theoretical perspectives on EMNEs’ internationalization with the observed firm motives and behaviors of our case firms. We propose a framework of multiple contextual settings to understand the context‐driven internationalization of the case firms. Finally, our article offers a set of propositions emphasizing firm‐level entrepreneurial orientation and international orientation, when EMNEs internationalize via CBAs in developed regions. © 2017 Wiley Periodicals, Inc.     

Export intensity of foreign subsidiaries of multinational enterprises: The role of trade finance availability

We examine the relationship between the role of trade finance availability and the export intensity of foreign subsidiaries of multinational enterprises (MNEs). In developing our hypotheses, we draw upon insights derived from “new” internalisation theory (international business literature) and international trade finance (international economics literature). We empirically test these hypotheses using survey data compiled from subsidiary managers in six ASEAN countries, supplemented with host-country level data. We conceptualise, empirically test, and establish that the subsidiary-level capability in combining and utilising internal and external debts is an important subsidiary-specific advantage to support export intensity. We find that subsidiaries employ intra-firm loans from MNE internal capital markets and, to some extent, bank loans from external financial institutions to boost their export intensity. Subsidiaries may have concerns about foreign exchange risks, but the use of appropriate foreign exchange risk management is positively associated with export intensity. We discuss the implications of our findings for theory and practice.     

The combined effects of dependence and relationalism on the use of influence in marketing distribution systems

This study uses data from the automotive replacement tire industry to test the proposition that dependence and relationship structure interact to determine frequency of influence-strategy use in distribution systems. The findings support the expectation that dependence is positively associated with recommendations, information exchanges, promises, requests, legal pleas, and threats. However, increases in dealer dependence increase the use of requests, legal pleas, and threats only in systems characterized by trivial levels of relationalism.The authors would like to express their gratitude to John Burnett, Robert Dwyer, Jule Gassenheimer, and Allen Wilhite for their helpful comments on this project.

Estimating Value Creation from Revealed Preferences: Application to Value‐based Strategies

Research summary : We develop and apply a new set of empirical tools consistent with the tenets of value‐based business strategies, leveraging the principle that “no good deal comes undone” and the methods of revealed preferences, to empirically estimate drivers of value creation. We demonstrate how to use these tools in an analysis of value creation in buyer–supplier relationships in the UK corporate legal market. We show that our approach can uncover evidence of subtle mechanisms that traditional methods cannot easily distinguish from each other. Furthermore, we show how the estimates can be used as parameters of biform games for out‐of‐sample analyses of strategic decisions. With readily available data on relationships between firms, this approach can be applied to many other contexts of interest to strategy researchers. Managerial summary : Managers need to understand the drivers of value creation for customers in order to make competitive positioning decisions and understand when they can capture value under competition. However, estimates of the relative importance of each driver are typically difficult to obtain. In this article, we help remedy this problem by demonstrating a novel method that obtains estimates of the contribution of various drivers of value creation from commonly available data of buyer–supplier relationships. These estimates can then be used to inform the strategy‐making process. Copyright © 2017 John Wiley & Sons, Ltd.
